Problem with great new bookmarks view

Hi, all!
I'm really glad Opera 25 features a bookmarks view, but need to mention that my "imported bookmarks" appear without any kind of order - alphabetical, or folders first, etc.
Is there any way to tidy things up, as these are the bookmarks I use most?

Go to the Opera menu, navigate to bookmarks and right click the folder you wish to order alphabetically. You will see 'Sort alphabetically' in the right click menu. This must be don't in the Opera menu and not the bookmarks manager, as the bookmarks manager does not currently support it.
